Abstract
Description
図6、図7は、時間及び/又は周波数が異なる複数の領域に設定されるPUSCHに対して上り制御情報をそれぞれ多重する場合の一例を示している。
<UCIの多重方法>
図6、図7では、UCIを同じ周波数領域において時間方向にわたって多重する場合を示したが、UCIの多重方法はこれに限られない。例えば、各PUSCH領域に多重するUCIを異なる周波数リソースに多重してもよい(図8参照)。
また、図6-図8では、上りデータ(各CB)のマッピングとしてオプションA及びオプションBの構成を適用する場合を示したが、本実施の形態が適用可能な構成はこれに限られない。例えば、図9に示すように、所定CB(ここでは、CB#0、#2)が複数のPUSCH領域(ここでは、第1の領域と第2の領域)にわたって配置されない構成に対しても本実施の形態のUCI多重方法を適用してもよい。
図6-図9では、3個のCBを送信する場合を例に挙げて説明したが、適用可能なCB数は3個に限られない。CB数は1個又は2個であってもよいし、4個以上であってもよい。なお、CB数が1の場合にはCB間におけるパンクチャ数のバラツキは生じないが、CB数が2以上の場合と同様にUCI多重を制御することにより、CB数に応じてUCI多重方法を変更する必要がない。この場合、UEにおける送信処理の負荷を低減することができる。
図6-図9では、1スロットを2個に分割した前半スロットと後半スロットに周波数ホッピングを適用して2個のPUSCH領域を設定する場合を示しているが、適用可能なPUSCH領域数は2個に限られない。例えば、3個以上に分割されたPUSCH領域を適用してもよい。また、複数のPUSCH領域をそれぞれ構成するシンボル数が異なっていてもよい。
以下、本実施の形態に係る無線通信システムの構成について説明する。この無線通信システムでは、上記各態様に係る無線通信方法が適用される。なお、上記各態様に係る無線通信方法は、それぞれ単独で適用されてもよいし、組み合わせて適用されてもよい。
図11は、本実施の形態に係る無線基地局の全体構成の一例を示す図である。無線基地局10は、複数の送受信アンテナ101と、アンプ部102と、送受信部103と、ベースバンド信号処理部104と、呼処理部105と、伝送路インターフェース106とを備えている。なお、送受信アンテナ101、アンプ部102、送受信部103は、それぞれ1つ以上を含むように構成されてもよい。
図13は、本実施の形態に係るユーザ端末の全体構成の一例を示す図である。ユーザ端末20は、MIMO伝送のための複数の送受信アンテナ201と、アンプ部202と、送受信部203と、ベースバンド信号処理部204と、アプリケーション部205と、を備えている。
なお、上記実施の形態の説明に用いたブロック図は、機能単位のブロックを示している。これらの機能ブロック(構成部)は、ハードウェア及び/又はソフトウェアの任意の組み合わせによって実現される。また、各機能ブロックの実現方法は特に限定されない。すなわち、各機能ブロックは、物理的及び/又は論理的に結合した1つの装置を用いて実現されてもよいし、物理的及び/又は論理的に分離した2つ以上の装置を直接的及び/又は間接的に(例えば、有線及び/又は無線を用いて)接続し、これら複数の装置を用いて実現されてもよい。
なお、本明細書において説明した用語及び/又は本明細書の理解に必要な用語については、同一の又は類似する意味を有する用語と置き換えてもよい。例えば、チャネル及び/又はシンボルは信号(シグナリング)であってもよい。また、信号はメッセージであってもよい。参照信号は、RS(Reference Signal)と略称することもでき、適用される標準によってパイロット(Pilot)、パイロット信号などと呼ばれてもよい。また、コンポーネントキャリア(CC:Component Carrier)は、セル、周波数キャリア、キャリア周波数などと呼ばれてもよい。
